Be it known that I, Mosns MosLnn, a c'i'tizen of the United States, residingat New Yo'rk,'New York county, New York, have invented certain new and useful Improvements in Round-Door Safes, of which the following isaspecification.

In my Patent No. 788,325, of April 25,-

' 1905, I set forth a safe with tapering round drawings, in which' door heldin the door-opening by studs proj ecting inwardly from the door-jamb and en gaging locking-recesses in the periphery of the door.

My present invention, while following my former patent in a general way, provides important improvements.

My present invention will be readily understood from the following description, taken in connection with the accompanying Figure 1 is a front elevation of a rounddoor safe exemplifying present invention; Fig. 2, a horizontalsection through the front wall thereof, the door appearing partly in horizontal section; Fig. 3, a horizontal section, on an enlarged scale, through-a portion of the door and door-jamb at one of the locking-studs and Fig. 4, a vertical section, on an enlarged scale, through a portion of the door in a plane parallel with its face.

In the drawings, 1 indicates the general body of the safe 2, its front Wall; 3 the circular door-o )ening therein; 4, the outer portion of the oor-open ing, the same be ing ta pering, with its smaller part inward; 5, the inner portion of the door-opening, the same being straight or without taper; 6, the door considered as a whole; 7 the outer portion of the door, the same being tapering and fittin the "tapering portion of the door-jamb witfi accuracy, as by having been ground to place;

8, the inner portion of the door, the'same being cylindrical and adapted to the inner .portion of the door-j amb with perfect freedom of fitting; -9, studs, of which there may be one or more, four being shownin the example, these studs being rigidly held .in the doorjamb and projecting nwardly therefrom, the

. ing portions, and a cooperating recess and projecting portion of the studs being convex and the bodies of the studs where they; are

held in the door-jamb being-perfectly cylin-' drical, these studs being illustrated as projecting inwardly from the non-tapering portion of the door-opening, and10 shallow recesses, onefor each stud, formed in the periphery. of the door, the recesses being concave'in cross-section and leading forwardly .and then circumferentially 'witha helical trend, so that by turning the door when the studs are in engagement with the recesses the door will be drawn inwardly. 1

Asthe devices for supporting and operating the door may be-of any usual or suitable construction, I do not herein consider it necessary to refer to their details. I,

By reason of the combined tapering and non-tapering features of door and doorjamb a good thickness is.secured,while at the same time the necessary accuracy of fitting may be concentrated upon a portion only of the thickness, and the perfection of the accurately-fitting surfaces is not interrupted or interfered with either in original construction or in subsequent use by the studs or recesses. l l

The slightly-projecting convex studs, in conjunction with .the shallow concave recesses,provide'in a niost admirable degree for satisfactory locking and at the same time provide practically.',co ntinuous surfaces at door rim and jamb free from. corners or angles, thus permitting not only of ready cleaning, but avoiding the possibility of the lodgment of foreign matters to interfere with the proper coaction ofthe studs and recesses. f

I have'employed the terms -lockand locking in connection with the studs and recesses; but'it is to be understood that this applies to the function. ofthese parts in pre venting the outward movement of theldoor after it has been seated and turned. The

actual lockin of the'door' to prevent its being opened by being turned in the reverse- .direction will-of course be takencare of by the usual locking. accessories.
